Painting Magnolia over Grey Walls

How dark is grey?

When repainting dark to light it's often worth repainting into 'one-coat' white first.

Also, have you mixed your magnolia paint really well?

Trying to paint over white is equally as bad, but on the other end of the scale.

I disagree. Magnolia is MUCH closer to white than to dark grey. The bigger the difference, the bigger the problem.

Of course, when painting dark over light, the difference is less important.

I sort of agree with you as it uses my kind of logic but given magnolia and white are a similar price you may as well put extra coats of magnolia on rather than introduce a coat of white?

White paint is usually cheaper, one-coat white is easier to find than one-coat magnolia (or other). And for under-coat paint you don't need top quality, just good adhesion.

Bear with it.
I recently tackled artex ceilings that had never been painted. It was hard work and each time I thought I'd got it perfect until it dried out but in the end, 3 coats, i got it and it was worth doing.
Grey is a hard colour to change. The tinge shows through. Pink is another youd think was easy to cover but not.

These days I use Zinsser cover up primer on everything before changing the colour. One coat over dark red and it looked like a white room. Then two coats of pale blue emulsion = perfect.  I hate the primer, it's stinky and gloopy, but it's also magic and well worth the little extra effort. I am sure other brands available - I stumbled across this one at the start of my DIY adventure and I don't fix things that are currently not broken

Thanks , Its just that I got fixed in my mind that the norm is 2 coats, I have had my 'awakening' through my post that it is not !

If you are not already using a paint scuttle such as in the link below then get one. Those paint trays are useless. It might be a bit basic for you but Painting and Decorating on YouTube do a video I think called how to load your roller.

I must admit that I didn't know to run the roller under the tap to wet it then spin out the excess water prior to starting until a couple of years ago.

Great Youtube channel, I wonder why I never bumped into this channel when I searched about Painting on youtube.. Weird search algorithms ... 
I don't have the scuttle -  I will buy one.  Thanks !

Another fan of Zinsser products. I managed to paint over a “feature wall” that had been painted midnight blue and I painted it white. The rest of the walls were already white but I used the same paint so it was the same tone of white throughout. No one can tell that wall was ever another colour.

I'd agree with some of the points already made - two coats of good quality paint will normally do the job, as long as each coat is given time to properly dry.  The wall should be prepared too, a wipe down with soap and water to shift dust and grime (and allowed to dry).  The final colour may take a full day to fully take hold and to block out the previous colour.  Paint that comes in the large 10L buckets tends to be poor quality and thin, therefore requiring more coats (usually only good for refreshing a wa;; already painted in the same colour).

I painted over pale green paint with Dulux Barley White, it took 5 coats in some places.
